High frame frequency sun sensor and implementing method thereof

The invention discloses a high frame rate sun sensor. The sensor realizes high data update rate of the ROI-based window dynamic tracking through an image acquisition module, a calculation module, a prediction module and a first control module. The invention further discloses a realization method of the high frame rate sun sensor; the method utilizes the current solar facula image and coordinates of center of mass of a facula which is corresponding to a same small hole obtained by the former solar facula image to predict the position of the facula which is corresponding to the small hole in thenext solar facula image, thereby realizing the ROI window dynamic tracking; compared with the sun sensor which is based on the full-frame image collection, the high frame rate sun sensor greatly reduces data of a background pixel region. The use of the high frame rate sun sensor and the realization method can reduce the amount of the data which needs to be processed for obtaining attitude information and improve the data update rate of the sun sensor.
